50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
Answer: 16 ounces : 1 pound
Answer: 35
Step-by-step explanation:
We substitute a for 1 and b for 6.
5(1+6)=5(7)=35
Regardless of the size of the square, half the diagonal is (√2)/2 times the side of the square.
The ratio is (√2)/2.
_____
Consider a square of side length 1. The Pythagorean theorem tells you the diagonal measure (d) is ...
... d² = 1² +1² = 2
... d = √2
The distance from the center of the square to one of its corners (on the circumscribing circle) is then d/2 = (√2)/2. This is the radius of the circle in which our unit square is inscribed.
Since we're only interested in the ratio of the radius to the side length, using a side length of 1 gets us to that ratio directly.
